In the unix-pc.general newsgroup, someone mentioned that in the way the
machine was designed that it was incapable of running both serial ports
in this manner at the same time.

The solution is one I mentioned at Usenix in June which was to make an
intelligent ports card for the UNIX-pc.  Good luck! :-)

Communications between a serial port and the console are relatively (if
not completely) flawless.  If you set-up your Trailblazer according to
Lenny Tropiano's tb-setup scripts and use hardware flow control, you
can (to any reasonable expectation) assume that the Trailblazer is as
good as being there.  I, myself, have never gotten ANY line noise running
using PEP, but I definitely have at 2400 baud.

If you need the tb-setup script, check-out the posting I made to the unix-pc
distribution about the ICUS archives, or e-mail me for more information.
